Title: Improved method of depositing bright-nickel/chromium
Inventor: ODEKERKEN JULES MARIE
IPC: C23C18/36
Filed: 1964-04-01
Abstract: A microporous chromium layer is formed on a bright-nickel layer e.g. on a steel plate substrate by applying an intermediate layer, e.g. by electrodeposition or chemical plating from a separate bath, after applying the bright-nickel layer but before applying the chromium layer, said intermediate layer being a metal or alloy containing at least two insulating materials of different average particle sizes, the larger or largest average particle size being 0.5-5 microns and the smaller or smallest being no more than one tenth of the larger or largest size.  The insulating materials may be only one substance or different substances, e.g. Cr2O3 of average size 0.5 micron with amorphous SiO2 of average size 0.025 micron.  Examples of plating baths for the intermediate metallic layer with particles of insulating materials kept in suspension by stirring or air insufflation are:- (1) cobalt/bright-nickel bath containing NiSO4, NiCl2, CoSO4, H3BO3, Ni formate, HCHO with BaSO4 and cellulose; (2) dull-nickel bath containing NiSO4, NiCl2, H3BO3 with kaolin and SiO2; (3) cobalt/tungsten bath containing CoCl2, sodium tungstate, Rochelle salt, NH4Cl with acrylate dispersion and polystyrene powder; and (4) reduction nickel bath containing NiCl2, sodium citrate, NH4Cl, NaH2PO2, NH4OH with P.V.C. powder and Al2O3.  The initial bright-nickel layer may be electrodeposited from a bath containing NiSO4, NiCl2, H3BO3, 1, 4-butinediol, paratoluene sulphonamide and sodium lauryl sulphate; the final chromium plating may be effected in a chromicsulphuric acid bath.

Abstract: 310,890. Michel, M. May 2, 1928, [Convention date]. Wireless tuning - apparatus, adjustment devices for.-Apparatus for providing a single control for all the adjustable elements in, for example, a wireless station has shafts coupled by worm or other reducing gearing by which approximately independent adjustment of two condensers mounted on these shafts is obtained from a. single knob, a range-changing switch being operated by the slow-motion element. A condenser 2 has its movable vanes mounted on a shaft 3 which is rotated directly by a knob 1 and is coupled by a worm 4 and worm-wheel to a shaft 6 carrying the movable vanes of the second condenser 7 and also contact brushes rubbing on divided fixed annular contacts 8 by means of which the connections of an inductance coil are changed for altering the range of wave-length. In order to reduce the motion of the condenser 7 for the complete range zeromaximum-zero of the condenser 2, the movable plates of the latter may be so shaped that this complete change takes place in half a revolution instead of a complete revolution. A disc 10 rotating in front of an opening 11 in a fixed plate 12 may indicate stations. A large range of capacity variation may be obtained by using a variable condenser of say 0.0001 microfarad controlled by a single knob at the same time as a contact device which introduces additional constant capacities. The Specification as open to inspection under Sect. 91 (3) (a) states also that a variable condenser may similarly be connected to a potentiometer or a tuning condenser for a frame aerial and the device directing the frame. This subjectmatter does not appear in the Specification as accepted.

Filed: 1976-04-06
Abstract: 1495113 Friction clutches CATERPILLAR TRACTOR CO 6 April 1976 [9 July 1975] 13858/76 Heading F2C In a friction clutch for a motor vehicle wherein the centrifugal pressure of liquid in a chamber 54 formed within a driving housing 32, 33, 34, 36 acts against the bias of clutch disengaging springs 57 through a piston 51 and springs 56 on a presser plate 47 to engage clutch plates 44, a liquid supply 71 for charging the chamber 54 and for cooling and lubricating the clutch plates 44 is reduced by a valve 82 when the clutch is disengaged to prevent viscous drag between the clutch plates. During clutch disengagement the presser plate 47 acts through its hub 48 to move a valve sleeve 83 left and block the flow of liquid between the sleeve 83 and a flange 79. Thereafter the chamber 54 and a reserve fluid retainer 89 are maintained full by flow through orifices 88. During clutch disengagement, due to a decrease in the centrifugal pressure in the chamber 54, a washer 66 fast with the piston 51 engages the presser plate 47 to positively withdraw the latter. The clutch may be disengaged whilst the centrifugal pressure is above the clutch engaging valve by supplying pressure to a clutch disengaging servo 61 which acts through rods 58 on the presser plate 47. Light springs 63 maintain the clutch plates in contact during clutch disengagement to provide a small torque to an output shaft 26 and thus facilitate ratio shift in a following change speed gear. The piston 51 abuts the end of plate  carrying part 34 of the housing to limit the  maximum clutch engaging pressure.

Filed: 1951-06-12
Abstract: 699,873. Hand-turning gear. SILBERSTEIN, V. June 12, 1951, No. 13940/51. Class 7 (v) In an inertia starter comprising a flywheel 7 adapted to be rotated and then coupled to the crankshaft of an engine, means, such as weighted levers 8, for decoupling the flywheel 7 from the crankshaft when the engine has started, drive means, for example handle 17, a main drive connection such as shaft 18 and gears 12, 13, between the handle 17 and flywheel 7, an axially movable pinion 2 adapted to engage the engine and clutch means between the pinion 2 and flywheel 7, there is provided an auxiliary drive connection, for example shaft 18 and gears 5, 16, between the handle 17 and pinion 2 in parallel with the main drive connection and clutch, which is adapted to move the pinion into mesh with the engine before the clutch is engaged. Rotation of handle 17 is transmitted through bevel gears 19, shaft 18, ratchet 14 and step-down spur gearing 16, 5 to a threaded starting shaft 3 and so causes translation of pinion 2 into mesh with the engine flywheel 1 which is thereby slowly cranked. The pinion is prevented from turning during its meshing movement by means of a light spring 15. Rotation of shaft 18 is also transmitted by means of a further ratchet 21 and step-up spur gearing 13, 12, to the starter flywheel 7, which is axially slidable upon a shaft 11; when the flywheel 7 attains a given speed the. weighted levers 8 overcome a spring 9 and move outwardly under centrifugal action thereby clutching the flywheel to a member 6 on the starter shaft 3 and rotating the engine at high speed in the same direction as the slowspeed auxiliary drive. By disengaging ratchet 21 the handle 17 may be used to effect turning of the engine for adjustment or other purposes. Instead of having a common shaft 18 between the main and auxiliary drives, the latter may take the form of a belt drive, handle 17 being disconnectible from the bevel gears 19 by transposing ratchet 21 to a position between the handle and bevel gears, the ratchet becoming inoperative upon pulling the handle. Specification 697,873 is referred to.

Title: Improvements in or relating to mechanism for automatically severing the terminal threads of a stitched book or the like
IPC: B42B2/02
Filed: 1930-11-14
Abstract: 362,828. Book-stitching machines. POLLAK, J. E., 20, Holborn, London.-(Brehmer, Geb.; Plagwitz, Leipsic, Germany.) Nov. 14, 1930, No.13959/31. Divided on 362,132. [Class 112.] Thread cutters.-The terminal threads of a stitched book are automatically severed by a cutter associated with a thread selector both when an idle stitch is formed between the completely stitched books, as in the method of book stitches described in Specification 362,863, and when no idle stitch is provided. When the stitching needle 16 has completed the final stitch of a completely stitched book, the needle draws the thread c taut, Fig. 2. The thread guide 14a is then advanced by a timed mechanism to engage the inclined nose 18, Fig. 5, with the thread c. Continued forward movement of the guide 14a causes the thread to slip round the nose 18 and lodge behind the hook part. The thread is then carried down by the stitching needle 16 when this inserts the initial stitch into the next book signature and is so laid across the thread guide 14a to be retracted with the guide during its reciprocation. The thread is then brought into contact with the severing device 15. When the book is stitched w th both chain and zig-zag stitches, the thread is carried along the guide 14b, Fig. 5, which is timed to be in the retracted position when the stitching needle 19 is inserting stitches into intermediate sections of the book and until the needle has completed the terminal stitch of a book. The needle is then once more retracted and displaced laterally from the chain line position shown in Fig. 2, to the full-line position. At the moment the guide 14b is a dvanced so that when the needle 19 descends to insert the initial stitch into the next book, the thread c is laid across the guide 14b as shown by the dotted lines in Fig. 2. Retraction of the guide brings the thread into contact with the severing device. This mechanism is employed when stitching books with both kinds of stitches as shown in Fig. 4. The device may be used with a swinging saddle sheet feed 37, Fig. 8, in which case needles 44 move upwards to pierce the sheets and are followed by stitching needles 32 which cooperate with hooks 33, Fig. 9. In this case, an idle stitch is formed between the books. When the idle stitch is complete, a lever 26 is moved to actuate the slide bar 25 carrying the selector members 31 to move these forward so that the thread is laid over them when the needles form the first stitch in the new book. During the stitching of this book, the thread is pushed back on the selectors till it meets the cutter and is severed. Fig. 20 shows a modification in which the sheets are fed by a swinging carrier to curved needles 70 for forming chain and zig-zag stitches.
